【摘要】 本研究利用一个区域三维化学输送模式模拟研究了东亚地区2001年春季有机碳气溶胶的输送与演变过程.有机碳气溶胶浓度的模拟值与1RACE-P和ACE-Asia观测期间获取的观测值相比,模拟值与观测值之间具有非常好的一致性,模式合理地反映了有机碳气溶胶浓度的时空分布.模拟结果表明,有机碳气溶胶柱含量的高值区(大于16 mg/m2)主要集中在长江中游和西南地区,黄河以南的我国大部分地区柱含量超过了7mg/m2,并且4 mg/m2的等值线延伸到了西北太平洋深处.更多还原

【Abstract】 A regional three-dimensional chemical transport model was applied to East Asia to investigate transport and transformation processes of organic carbon aerosols in the spring of 2001. Comparison of simulated concentrations of organic carbon aerosols with some observed values obtained during the TRACE-P and ACE-Asia field campaigns indicates that there is a good agreement between simulated and observed values, and the model reproduces the time spatial distributions of organic carbon aerosols reasonably well. Simulation results show that high levels of column burden of organic carbon aerosols (larger than 16 mg/m2) concentrate in the middle reaches of Yangtse River and southwestern China, and in the most part of China to the south of Yellow River the column burden is over 7 mg/m2, while the isopleth of 4 mg/m2 extends to the inner part of northwestern Pacific Ocean.更多还原
